Title: Refuge guide device
Inventor: KOJIMA TADASHI
IPC: G08B27/00
Filed: 1990-01-31
Abstract: PURPOSE:To safely guide persons toward a refuge exit by switching and flickering plural light emitting bodies in the direction for refuge guide, which is discriminated by a room or a block from which an abnormality sense signal is sent, by this signal from a sensor. CONSTITUTION:LEDs 3-1 to 3-10 are always lit for guide. If a sensor 11 receives the abnormality sense signal from, for example, a smoke sensor (S) 2-1, a controller 13 controls and LED driving part 12 to switch and flicker LEDs 3-1 to 3-10 in the direction where persons should be guided to an emergency exit while avoiding the room. By this control, LEDs 3-1 to 3-10 are so switched and flickered that they are guided to the emergency exit while avoiding the room A as much as possible. Since the refuge direction is surely indicated by switching and flickering of light emitting bodies in this manner, they are safely and accurately guided toward the refuge exit.

Title: Monitor circuit for power source voltage
Inventor: MIURA TADAHIKO
IPC: G01R19/165
Filed: 1990-01-31
Abstract: PURPOSE:To monitor the most suitable voltage of the power source system even whichever of two power sources is adopted without increasing the quantity of terminals by detecting the range of the power source voltage with the use of plural comparators. CONSTITUTION:The ratio of voltage dividing resistors 16, 17 is settled so that an output of the comparator 1 is changed over at an intermediate value V2 of power source voltage in two power source systems. When the voltage is higher than a monitor voltage V3 in the higher voltage system, the voltage applied to the comparator 1 is elevated to be higher than a reference voltage VR, and a MOS transistor 26 is connected by this output to make an electric potential between voltage dividing resistors 20, 21 to the same as that of power source 13 at the lower potential side, and the power source potential is monitored by a comparator 2 in this condition. This action is inversed when the voltage is decreased than V2. As the result, when the output level of an output terminal 14 is HIGH, the power source voltage is indicated as normal, and the abnormal state is indicated if the output level is LOW. The power source most suitable for the power source system can be thereby monitored.

When currents are let flow to the exciting coils 7, with a potential difference given between the electrodes 9 and 14, Bragg reflection layers 3 and 8 and the active layer make a magnetic field in the direction of the optical axis 23 of a laser beam 1 work on it.  The laser beam source 1 radiates circularly polarized light. By the above, light containing more information can be generated by radiating the circularly polarized light with relatively small currents, and controlling the direction of polarization.

IPC: G03G15/08
Filed: 1989-02-03
Abstract: PURPOSE:To reduce the leakage of toner from a sealing part by arranging a plate between a mixer and a magnet roll. CONSTITUTION:Since toner 4 increasing its pressure by the rotation of the mixer 3 is shielded by the plate 1, the influence of the pressure is not given to the side of a magnet roll 2.
